If you believe the National Enquirer...

Country singer Mindy McCready is under investigation for any possible role she played in her live-in boyfriend’s shooting death.

Sources say he was cheating on her and possibly threatened to leave her on the day that he died.

A source told the tabloid, ‘David had been carrying on an affair for many weeks before the shooting. When Mindy found out, it fuelled a lot of very heated fights'.

‘The tension in their household became so unbearable that David packed up and left. He returned several days later to tell Mindy that he was going to leave her for good.’

Police in Heber Springs, Arkansas, have not said that there are any suspects in the case and their initial report on the shooting said that he died of wounds sustained by a self-inflicted gunshot wound.

In all previous reports, it was never clear if Mindy was in the house at the time that her beau shot himself on Sunday January 13, but in the Enquirer article, they allege that she was actually the one who made the 911 call.

According to the magazine, she told investigators that she did not hear the gunshot because the volume on the television set was too loud and that the emergency operator even heard a man moaning in the background when she was making the call.

The source says, ‘There [seem to be] a lot of elements to the case that police feel simply don’t seem to add up.'.

He shot himself to death at the home in Heber Springs, Arkansas, that they shared together.
